I recently had my new business cards printed at Crayton-Heritage Letterpress. They were able to achieve a deep impression in the 500gsm Somerset Paper that I chose. I had them use two Pantone colors so the cards would match my brand. The back is duplexed with a dark grey paper stock. I plan on carrying a white pen so that when I give someone my card, I can write where we met so they won't forget! Crayton-Heritage did an excellent job from start to finish. I highly recommend them for your letterpress needs.
